Kagohata | June 25, 1996 |
A car built-in type one-chip microcomputer including a ROM, a RAM, and an input/output port, wherein a control program which is executed on the car built-in type one-chip microcomputer is stored in a high level language, so that formation, change and verification of a control program can be easily carried out by an ordinary programmer who has never been trained to treat an assembly language. Even if the kind of the microcomputer is changed, it is not necessary to change the control program. The program can be modified as a result of experiment. A program developed by a program developing apparatus can be used, as it is compatible with the microcomputer.
